+Breaking: #78477 - FlashMessagesViewHelper no longer inherits from TagBasedViewHelper
+=====================================================================================
+
+See :issue:`78477`
+
+Description
+===========
+
+The :php:`FlashMessagesViewHelper` has been refactored and no longer inherits from the :php:`TagBasedViewHelper`.
+
+
+Impact
+======
+
+The :php:`FlashMessagesViewHelper` outputs default context specific markup. Adding own classes or tag attributes is no longer possible.
+
+
+Affected Installations
+======================
+
+All installations using the :php:`FlashMessagesViewHelper` with tag specific attributes.
+
+
+Migration
+=========
+
+Remove the tag specific attributes and style the default output. If you need custom output use the possibility to render FlashMessages yourself, for example:
+
+.. code-block:: html
+
+	<f:flashMessages as="flashMessages">
+	    <dl class="messages">
+	        <f:for each="{flashMessages}" as="flashMessage">
+	           <dt>CODE!! {flashMessage.code}</dt>
+	           <dd>MESSAGE:: {flashMessage.message}</dd>
+	        </f:for>
+	    </dl>
+	</f:flashMessages>
